nornnx PAPER TABLE.

Application filed January To all whom it may concern:

Be it known that I, FREDERICK W. BER- NAU a citizen of the United States, residing at ldetroit in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Duplex Paper Tables, of which the following is a specification. 1

The object of my invention is to provide I a duplex or double-decked paper table for the carriages of typewriters and printing calculating machines. I

The invention contemplates theprovision of a paper table having decks arranged one above the other, with superposedparts extending under the platen, whereby a master sheet and a carbon sheet of paper may be fed to, and around, the platen'from the upper face of the upper table or deck, and a second sheet, or set of'sheets, with, or without, a carbon sheet, may be fed from the upper face of the lower deck- Or -table to, and around, the platen to overlie the master sheet. By this arrangement when an 'imprint of the printing elements is made on the second sheet, a carbon impression will be made on the master sheet and, thereafter, the second sheet or sets of sheets may be removed, without disturbing the master sheet and carbon sheet, whereupon another sheet or set of sheets may be introduced, receive the printing impression and a carbon copy thereof be transferred to the master sheet, and so on. Thus, the invention provides im roved means, enabling the master sheet to e retained around the platen and used to accumulate, in succession, duplicates of the date printed on successive, individual, papers such as bills, checks, lists, etc.

The arrangement, and adaptability, of the respective decks or tables is such that the master sheet is held against the platen and does not interfere with the introduction of successivebills, checks, or other papers, as the-latter may be pushed along the under tableiior deck and around the platen, in overlying relationship to the master sheet when the compression rolls are released. Then, when the new sheet is properly positioned, the compressionfirolls are allowed to ress against the sheets, whereupon all .0 the sheets are arranged to be fed together when the platen is spaced or turned.

be used to hold the sheets against the face of the. platen, as usual in paper carriages. A practical embodiment of the invention is described hereinafter and is shown in the accompanying drawings but it will be understood that modification of the construct1on may be resorted to without departing from the principle of the invention.

In the .accompanying drawings:

Figure 1 is a front elevation of a paper carriage and its platen equipped with the present improvements.

Fig. 2 is a similar view, certain parts being broken away for the purpose of more clearly disclosing the invention.

Fig. 3 is a right hand end elevation; and

Fig. 4 is a section on the line 44, Fi 2 dotted lines representing the master sh and the individual sheet, such as a bill, check, or the like. v 7

The platen 1 has its axle 2 mounted in the ends or plates 3 of the carriage.

The compression, paper holding, rollers or rolls 4 are journaled in sub frames 5 which" are swiveled at 6 in a frame 7 which is hinged at 8 to the ends 3, suitable spring means being provided by which thecompression'rolls are normally urged toward the platen for the purpose of holding the pa r.

X paper release lever 9 is carried by a rod 10 mounted in the ends 3. Normally the lever 9 is in the position shown in Fig. 3, whereupon a groove 11 receives points or cams 12 on the frame pieces 7, thereby permitting the rolls 4 to bear against the platen 1 or against the paper. When the lever 9 is swung to the dotted line position of Fig. 4, the turning of the rod or shaft 10 releases the rolls 4 from the aper.

Extending across t e front of the platen and connected to the ends 3 is a bar 13 which carries any desired, or preferred, paper holding fingers 14 having the usual rolls 15. Other paper fingers 16 are also carried by the bar 13.

As thus far described no invention is,

claimed by me as the aforesaid elements are 7 eet well known and may be changed without affecting my invention, whichwill now be set forth.

Carriages having platen, paper rolls, etc., are usually provided with a table or deck for guiding the paper to the platen. Such a table or deck is shown at 17 as being suitably connected to the ends 3 and having a trough-like, curved, part 18 located below the platen 1. The trough-like part 18 has slots 19 to receive the rolls 4 so that they may press against the paper.

My invention resides in an upper table ordeck 20 of less height than the deck or table 17 and supported therefrom by end s acers to form a compartment above the eck 17, and in the combination of the two tables or decks 17, 20, whereby a duplex paper table or deck is provided.

The upper table or deck 20 may be mounted in any desired manner so as to overlie the table or deck 17. The means shown for this purpose is a spacer 21 at each end of the deck or table 20 which is located between the two decks or tables and connected to them in any suitable manner as, for instance, by screws 22. The upper table 20 is thus separated from the lower table 17 by a downwardly converging compartment '23 whose ends are closed by the spacers 21. The upper deck 20 being of less height than the lower deck 17, the 1ndivid-' ual sheets, bills, checks, etc, may be readily dropped into the compartment between the decks and will be properl lined up by either spacer 21 without raving to pay special attention to placement, as would be the case if the deck 20 were considerably higher than the deck 17 and were the ends of the compartment open. Like the table 17, the table 20 is provided with a troughlike part located immediately under the platen as shown in. Fig. a. This troughlike part 20 preferably comprises curved fingers 20' which are best shown in Fig. 2.

The trough-like parts 18 and 20 are slightly spaced apart so that one or more sheets of paper may be passed between them after introduction into the compartment 23. The trough-like part of the table 20, that is, the fingers 20', 1S spaced slightly from the platen so that a sheet or sheets may be passed around the platen after introduction above said table 20.

'My, invention is susceptible of various uses but it is of particular use in enabling a tally to be kept of bills, checks, and other individual papers or sheets on which printed matter 18 recorded in a typewriter or printing adding or calculating machine. It is immaterial whether each individual check, bill, or paper be a single sheet or arranged dot the taking of one or more carbon co ies as the duplex table or deck enablas t e data printed on the individual aureate sheets to be accumulated on the tally or master sheet.

The master sheet 24 (with a carbon sheet, if none is used with the individual-sheet) is introduced to the platen above the upper deck or table 20 and the platen turned to run said master sheet into position. Assum ing it is now desired to record any matter on the individual sheet 25, or on said sheet and others associated therewith with interposed carbon sheets, the individual sheet 25 is introduced into the compartment 23 between the tables 17 and 20 and, the lever 9 having been turned to release the rolls 4, the individual sheet or sheets 25 may be pushed around to the front of the platen, through the space between the trough-like parts-18 and 20. The fingers 14 and 16 hold the sheets in' position and when the rolls 4 have been re-set so that the papers will be pressed against the. platen, the printing parts of the typewriter, adding or calculating machine may be used to print directly on the sheet 25 and to provide, by so doing, a duplicate impression on the master sheet 2 1. When the individual sheet 25 has received its impression, the rolls 4 are again released and said sheet may be pulled out without disturbing the master sheet 24. Another individual sheet 25, or set of sheets, may then be introduced into the compartment 23 and fed around into proper position to receive the desired impression. The master sheet 24 receives the same impression, through the carbon sheet. Thus, without disturbing the master sheet 24, it may be used to recelve a carbon copy of the data printed on successive bills, checks, and other papers and when the listing for the time being is complete, the master sheet can be removed and, if not'completely filled, it may be re-introduced into the machine and used to accumulate additional data when another set of bills, checks, or the like is made out.

I claim:

The combination with a cylindrical platen, and with the usual main paper table or deck which has an inclined part and a curvedor trough-like part extending forwardly underneath the platen and to the front side thereof, of a supplemental or additional paper table or deck of substantially the same length as the main table or deck supported above the main paper table or deck by end spacers disposed between the decks, said supplemental paper table being of appreciably less height than the usual main table or deck, said upper, supplemental deck comprising an'inclined part and a trough-like part, respectively, disposed wholly above the inclined and trough-like parts of the main table in spaced, but close, relationship thereto throughout their extent, and between them and the platen, the trou hlike part of the supplemental paper ta le extending to the front side of the platen, and paper rolls for holdin the paper against the platen, the space relationship 0 the upper and lower tables providing an unobstructed chute therebetween, down which the paper may be fed by gravity to said rolls, the upper part of the main paper table being exposed above the upper edge of the su plemental table, whereby introduc tion 0 papers between the tables is facili- 10 tated.

In testimony whereof I aflix my signature,
